APPARATUS FOR MIXING LIQUID AND POWDERED SUBSTANCES.

SPECIFI-JATION forming part of Letters Patent No. 399,276, dated March12, 1889.

Application filed July 10, 1888.

To all whom it mr/y concern.

Be it known that I, BENJAMIN DALTON MIL- LIKEN, of Somerville, in thecountyol' Middleand State of Massachusetts, have invented certainImprovements in Apparatus for Mixing Liquid and Powdered Substances andfor Filling Bottles and other Receptacles Thorewith, of which thefollowing is a full, clear,

and exact description, reference being had to i the accompanyingdrawings, making part of this specification, in which Figure 1 is a planof an apparatus of the class referred to constructed in accordance withmy invention. Fig. 2 is av side sectional elevation of the same. Fig. 3is a front elcvation, some parts being omitted. Fig. l is a horizontalsection on the line 1/ 1/ of Fig. 2. Fig. 5 shows the cups by which themixture is taken up to the spouts. Fig. (i represents theconveying-spouts; Fig. 7, a detail, (enlarged,) to be referred to; Fig.8, a removable nozzle.

The following devices, which, when assembled together, constitutes theprominent feature of my invention, are a revolving agitator for mixingthe ingredients, a strainer for eliminating foreign matter therefrom,and a cup 3 or series of cups for filling bottles or other receptacles,the said devices being so constructed and arranged as to simultaneouslyI perform their functions in a continuous, re- 5 liable, and harmoniousmanner.

In the said drawings, A represents a tank or receptacle preferably ofthe form of a cylinder or frustum of a cone within bearings, in which,to one side of the center of the same, is located an upright shaft, B,provided with a series of adjustable arms, a, carrying inclined blades0, the interior of the tank being also i of inclined blades, 0,

provided with a permanently secured. thereto at heights intermediate ofthe planes of two contiguous sets of blades,

l), which. is driven by a belt, 7). A short; distance above the tank theshaft carries a pin- 1 ion, c, which engages with a toothed wheel, E,having thereunder on its axis a pinion, d, Fig. 2, which drives apinion, c, which ongages with. a toothed wheel, G, secured to a shortstud, f, projecting up from its hearing The shaft 13 projects above thetank A and has secured to its top a pulley, 1

f is pivoted thebottom of an arm, 5 of a compound lover, I, the upperend of said arm being pivoted to the lower end of an arm, 71, pivoted toa long beam, K, whose lower end is pivoted to a standard, L, the severalpivotal points being capable of adjustment: and v the standard beingsupported in brackets 1' f. 7. is a fl'l("tl()ll\\'ll(30l on the underside of the arm 9 and located in the path of, the cam ii, on the uppersurface of which it rests.

To the upper outer end of the beam K is I pivoted the upper end of along rod, 1, to the foot of which is pivoted the middle of ahorizontalbar, "In, extending between vertical blocks :1 2/, which slide up anddown upon vertical guides o o, projecting up from the bottom of the tankA and. up through a wide slot, 2, cut in its top, the bar or and blocks12 n forming the cross-head T of the filling device now to be described.

q is a horizontal rod extending bet ween the sliding blocks 11 12 (belowthe bar 122) and having pivoted thereto a series of cups, M, each of theexact capacity of a bottle to be filled, t Fig. 6. The cups may bepivoted independently of each other, or may be pivoted in t groups tosaid rod g, each one, or one of a group, being provided at its bottomwith a teat or 5 projection, T, which, when the cups are full l andrising vertically from the tank, strikes 1 against a horizontalcross-rod, s, and tips the cups over into an inclined position, so as toempt their contents into a corresponding number of funnel-shaped spouts,N, separated from each other by partitions, Fig. 5, each cup drainingits entire contents into its proper spout. The lower end of each spoutis contracted to a diameter smaller than the mouth of the bottle, and isprovided with a re1novable tubular nozzle, t, to facilitate its beingcleansed should it become clogged, Fig. 8.

u is a horizontal brace for holding the tops of the vertical guides 0 0immovably in their proper relative adjusted position to insure the freereciprocatingmovement of the filling device, and also serves as a guardor stop for preventing the cups from swinging backward i out of theirvertical position, Fig. 7.

Rising from each side of the front of the tank in a position contiguousto the tops of the vertical guides 0 0 is a short standard, 1:, the topof which is connected by a brace, 7.1, with the top of the contiguousguide to give additional stiffness and security thereto, and the twostandards are connected by a horizontal brace, s, the rear surface ofwhich is located in or slightly in front of the vertical plane passingthrough the outer front surfaces of the cups and immediately in the pathof their teats or projections o", by which the cups are tipped into theposition for emptyin g their contents into their respective spouts Nwhen ascending from the tank through the slot 1) in its top.

The empty cups during their descent into the tank and when full duringtheir ascent are kept in a vertical position by a piir of upright rodsor guides, 10, secured at their bottoms to the bottom of the tank, thetops of these guides extending up to within a short distance of thehorizontal brace s, the front of the cups bearing against the guides 16until nearly into their position to discharge their ontents into thespouts, being held in their upright position till they pass above thebrace s.

P is a sheet of wiregauze attached to a frame secured in a verticalposition within the tank a short distance back of the path of thereciprocating filling device, the function of this gauze sheet being tostrain the liquid contents of the tank and prevent the passage into thecups of any foreign matter-such as pieces of wood or solid or fibroussubstances which may chance to be in the ingredients mixed together inthe larger (rear) portion of the tank, this strainer also serving toprevent any agitation of the mixture within the smaller front portion ofthe tank in which the filling-cups are located, and avoiding anysplashing over of their contents when full.

Operation: The liquid ingredients being poured into the tank A, thevertical shaft B is rotated, causing the inclined blades C to stir themtogether and dashing them against the stationary inclined blades C,secured to the interior of the tank, after which the powdered substancesare added and the ingredients thoroughly incorporated, the powderedsubstances being held in solution, as desired, by the revolving mixer.The parts being in the position shown in Fig. 2, with the highest point,17 of the cam -H under the friction- Wheel 15 of the arm g, and theshaft B revolving, the filling-cups are at their highest elevation. Asthe cam continues to revolve, the point 17 passes from under the wheelis and the cups M are free to descend by gravity through the slot 1;into the tank and into the mixture, which, by reason of the strainer P,is brought into a quiescent state in the portion of the tank in front ofit. As the cam continues to revolve, the filling-cups ascend, and justbefore the highest point, 17, of the cam passes under the friction-roll7c the projections on the under side of the cups are brought intocontact with the under side of the horizontal brace s, and the cups aretipped into a position for them to empty their contents into theirrespective spouts N, from the nozzles of which the contents flow intothe bottles held thereunder, the contents of each cup being of the exactcapacity of each bottle to be filled. A series of bottles having beenfilled, and as the cups are again descending for another charge, anotherset of bottles are broughtinto position with their mouths surroundii'igthe nozzles, the vertical guides keeping the cups in their uprightposition till they are again filled, and while they are rising untiltheir front surfaces pass above the guides and their projections 0'again come against the under side of the brace s, by which they areagain tipped and emptied, the several operations of mixing theingredients, strainingthem of impurities, filling the cups, and emptyingtheir contentsthrough the spouts into the bottles, being performed in acontinuous and reliable manner.

When it is desired to discontinue filling bottles, it is simplynecessary to place a stop under one of the sliding blocks 12 n of thecross-head of the filling device, when it is raised to its highestelevation by the pointl? of the cam coming under the friction-roll k.This can be done by hand or by any wellknown automatic device.

hen the filling-cups are arrested from moving, the shaft and itsagitating-blades C may continue to revolve and the ingredients be mixedand thoroughly incorporated independently of the operation of fillingthe bottles.

One of the uses to which my improved apparatus may be applied is themanufacture of stove-en amel, &c.,which is composed of certain liquidand powdered ingredients; but it is evident that other liquids forvarious purposes, or powdered substances only, may be mixed and filledinto bottles or other receptacles by my apparatus in the same continuousand satisfactory 'mau uer."

I claim The tank A, with a slot, 1), in its top, a strainer, P, locatedin the tank, one or more filling-cups, M, pivoted to a reciprocatingcross-head, T, a series of levers connected with the cross-head, and oneor more spouts, N, in combination with a revolving mixer, a series oftoothed gear actuated by the shaft of the same, and a cam, H, secured toone of said gear, one, of the levers connected with the cross-head beinglocated in the path of said cam and being periodically raised there by,all constructed to operate substantially in the manner and for thepurpose specified.

lVitness my hand this 16th day of June, 1888.
